m 6 272 MM/ JOHN P. KENNY, OF ROCHESTER, NEW YORK.-

PNEUMATIC SOLE FOR SHOES AND BOOTS.

Specification of Letters Patent.

Application filed March 13,

Patented Mar. 18, 1913.

1912. Se1'ia1 No. 683,613.

To (m about it may concern lie it known that 1, JOHN P. KENNY, a citizen of the United States, residing atthe city of Rochester, in the county of Monroe and State of New York, have invented .a new and useful Pneumatic Sole for Shoes and Boots, of which the following isa specitication.

boot or shoe that will not slip uponany surface when used by a runner, and which shall be durable, etiicient, and neat in appearance. l' accomplish these objectsby the construction illustrated in the accompanying drawing. in which l igure l is a side view of a shoe with my pneumatic sole atlixed. showing upper and lower layers of the. sole; the surrounding wall intervening said layers at their periphery; the air-chamber within, and the heel; Fig. 2 is a longitudinal sectional view, showing the interior thereot. and Fig. 3 is an enlarged vertical sectional view, showing method of attachment of the heel, the. position of the air valve and of the. retaining plate of the heel.

Similar numerals refer to similar parts throughout the several views.

Referring to the accompanying drawing by numerals. it will be seen that my improved pneumatic sole comprises an inner lining comprising upper and lower Walls 1, constructed preferably of canvas, said lining being incloscd by a coating of rubber Q, the outer or lower layer being made the thicker. a side wall 3 preferably of soft but heavy rubber with or without the canvas lining intervening said layers exleriorly and providing an air chamber 4 centrally, said layers being preferably vulcanized to the side wall, a plate 5, provided with prongs t3, 7 and 8, said plate being embedded Within said lower layer of the sole, the prongs 5o valve 10, through which air is injected in inflating said air chamber, a heel-retaining plate 11, provided with perforated shoulders 12 and 13, which are threaded Within and engaged by screws 14 and 15, any desired number of each being used in securing the heel, said heel-retaining plate being embedded within said lower layer of the sole, as shown, and anchorages 16 and 17, through which i said screws pass and whereby the heel is securely but removably attached to the sole.

My pneumatic sole for boots or shoe may be constructed by coating the upp lower body or lining walls 1 with rubber, insert-ing the side walls 3 between them and then vulcani zing the assei'nbled parts securely together to form a unitary one-piece structure into which the beforementioned plates, if used, and the air valve are incased in the positionsdescribed. Of course, the rubber coating on the lower w'all should be the thicker because of the wear tof which itis necessarily exposed, but the $016; as a whole should be sutlicientlyheavy and,therefore, of sufficient sti't'lness, to hold its form whenceme'nt'ed or sinnlarly secured wlth its upper wall againstthe sole of a shoe,

that is, aside from the distortions incident merely to the slight compression and expansion due to the weight of the wearer inv walking; This pneumatic s'ole can be readily attached to any shoe, ZIS'IS evident, and can be secured to the bottom of the shoe either by stitching or cemented thereto. This sole may. of course. be constructed Without the heel or the aforementionedprongs.

hat I claim:

As an a rticlo of manufacture, a pneumatic sole for shoes comprising upper and lower spaced walls composed of an inner body or lining of canvas or similar fabric and a thick outer 'rubber covering, and intervening side walls of rubber following the periphery of the first mentioned walls and the contour of the foot, to constitute an air chamber jointly therewith, all of said walls and their component parts being vulcanized together to form a unitary one piece struc ture of sufiicient weight and stifi'ness to hold its fol-n1 when cemented or similarly secured with its upper wall against the sole of a shoe and means for permitting the introduction of an under pressure Within said chamber.

JOHN KENNY.
